如何向mysql的一个字段写入数组？

UPDATE TeacherInfo set PhoneNumber = '[1234,1254]'

1、必须保证被更新字段的类型是字符型；

2、被更新的值需要用''包裹起来。

$sql = "SELECT key1,key2 FROM keyst"

$res = mysql_query($sql,$db_link)

$search = array()

$replace = array()

while($row = mysql_fetch_assoc($res)){

$search[] = $row['key1']

$replace[] = $row['key2']

}

$ftext = str_replace($search,$replace,$ftext)
